-----------------------------------
Summary: Beeline should detect conflicting authentication methods
Key: HIVE-17461
URL: https://issues.apache.org/jira/browse/HIVE-17461
Project: Hive
Issue Type: Improvement
Components: Beeline, JDBC
Reporter: Peter Bacsko
In Oozie, we pass "-a delegationToken" in the command line when we invoke
Beeline in a Hive action.
In one of our test, we accidentally defined "principal=" in the JDBC URL. In
this case, HiveConnection ignored the delegation token setting and tried to
authenticate via Kerberos, which didn't work inside a YARN container. We found
this behavior very confusing.
So either BeeLine itself should detect such inconsistencies or alternatively
HiveConnection could take care of it. Looking at the code, the "-a
delegationToken" does not matter that much inside
HiveConnection.createBinaryTransport() - if there's a principal, it will use
Kerberos, then it looks for delegation tokens, then finally it falls back to
plain authentication.
